EYEGLASSES.

Specification of Letters Patent.

-' Patented Aug. 8, 191%.

Application filed February 29, 1916. Serial No. 81,103.

To all whom it may concern:

Be it known that I, HUGO BRINKHAUS, a citizen of the United States, residing in the borough of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improve ments in Eyeglasses, of which the following is a specification, reference being had therein to the accompanying drawings, forming part thereof.

My invention relates to eyeglasses of the pince-nez type and is an improvement upon the invention disclosed in my application for patent for pince-nez filed August 3, 1915, Serial No. 43,420.

Important objects of the present invention are to simplify the construction, decrease the cost of manufacture and improve the appearance of the pince-nez.

Other more particular objects and advantages of my invention will hereinafter appear.

In carrying out my former above noted invention, I employed a comparatively rigid lens-supporting bridge piece and a separate transversely extending placketcarrying spring member, lever arms being connected to the plackets and pivoted upon the bridge piece for operating the plackets to move them apart against the tension of the spring member.

According to an important feature of my present invention, placket-operating levers are employed in combination with a combined bridge and spring member, the lenses being carried by the spring member, the transverse portion of which is preferably stiffened. Also in carrying out my invention, the lens supports and-the placket-op crating levers, as well as also the plackets or nose guards, may form extensions of such spring member which may be formed in one piece or integral therewith.

My invention further includes features of construction and combinations of parts as will appear from the following description.

I shall now describe the several pince-nez constructions illustrated in the accompanying drawings as embodying my invention and shall thereafter point out my invention in claims.

Figure 1 is a perspective from the rear and above of a pince-nez embodying my invention, parts of the lenses being omitted,

and Fig. 2 is a plan of the same. Fig. 3 is a view similar to Fig. 1 of a modified construction of which Fig. 4 is a plan. Fig. 5 is a rear elevation of a further modification of which Fig. 6 is a plan. Fig. 7 is a rear elevation and Fig. 8 a plan of another modified construction. Fig. 9 is a rear elevation and Fig. 10 a plan of yet another modification of th invention.

In all of the constructions or modificatlons of my invention illustrated in the ac companying drawings, a single lens-supporting and placket-carrying transversely arranged member is employed and is a spring member formed from a strip of metal which is shown as bent in its connecting portion and in its spring-forming portions substantially to the shape of the capital letter C.

In the construction embodying my invention illustrated in Figs. 1 and 2, a lens-supporting and placket-carrying spring member is employed shown as formed from a flat strip of metal and having a wider and correspondingly stiffer upper slightly curved connecting portion 1 arranged transversely substantially horizontally. Reduced and correspondingly more flexible end portions 2 of the spring member are horizontally curved rearwardly and inwardly so that these horizontally curved flexible spring extensions 2 of the stiffened transverse connecting portion 1 formtogether therewith. substantially 'a capital letter C arranged transversely. Somewhat wider downwardly turned continuations of the flexible spring ends 2 form nose-engaging plackets or guards 3, as appears in the drawings. The spring member at the ends of its middle stifiened transverse portion 1 is bifurcated or split to form lens-supporting extensions 4 which extend slightly rearwardly downwardly and outwardly and at their ends are provided with usual clips or mounts 5 for supporting usual lenses 6. Spring-controlling placket-operating lever arms 7 are shown as forming integral forward projections from the upper ends of the plackets 3, and these lever arms 7 extend forwardly and outwardly and at points intermediate of their length are pivoted by means of pivot studs shown as pivot screws 8 upon leversupporting lugs 9 formed from the same piece of metal as and bent over from the spring member and shown as bent out 7 wardly and downwardly from the upper part of the lens supports 2 adjacent to the stiffened middle "portion 1 of the spring The member, as appears in the drawings. front ends of the pivoted placket-operating lever arms 7 are adapted to be gripped by the fingers andpressed together for moving apart the nose-engaging plackets 3 against the tension of the spring member, which is the most yielding in its curved flexible end portions 2 and but slightly yielding in its stiffened middle portion 1, as will be readily understood. The nose-engaging plackets 3 are shown as provided with usual pads or plates 10 which may be of any usual or suitable material, as is understood in the art. The modified construction illustrated in Figs. 3 and 4 differs from that just described, in reference to Figs. 1 and 2, in that the placket-operating lever arms 11 project forwardly integrally with and from substantially middle points of the plackets 12 and are pivoted upon the lower horizontally outturned ends of the lenssupports 13, which are formed integrally with and as extensions of a horizontally curved spring member having a wider and stiffened middle portion 14: and more flexible curved end portions 15, in this respect being similar to the first described construction, and the operation or manner of use is substantially the same.

In the further modified construction illus trated in Figs. 5 and 6 the lenses 16 are shown as supported by means of usual metal bands or rims 17 and distance blocks or posts 18, upon the plackets 19, and are shown in the drawings as supported at the lower ends of the plackets. In this construction the plackets 19 perform a double function, serving as nose-engaging guards or plackets and as lenssupporting members which take the place of the lens-supporting extensions, such as 4:, illustrated in Figs. 1 and 2, or of the similar lens-supporting extensions 13 illustrated in Figs. 3 and 415' A single lens-supporting and placket-carrying spring member has a wider and correspondingly stiffer middle transverse portion 20 which gradually tapers into horizontally curved narrower resilient members 21 which, similarly to the two hereinbefore described constructions, are turned downwardly and widened to form the plackets 19., Placketoperating lever arms 22 extend forward integrally from the upper ends of the plackets 19 and at middle points are pivoted by means of pivot studs 23, shown as rivets, upon lever-supporting lugs 24:, shown as turned over rearwardly in L-shape from the lower edge of the transverse stiffened portion 20 of the spring member adjacent to the points where it merges into the resilient curved spring placket-carrying ends 21, as appears in the drawings. The positioning and pivoting of the placketbperating lever downwardly to form the plackets 28.

the same as hereinbefore described, excepting that in the construction illustrated in.

Figs. 5 and 6, the lenses 16, by reason of their being mounted upon the plackets 19,

will partake of the movement of the plackets. This movement of the lenses 16 being in horizontal planes,by reason of the horizontally extendingcurved spring ends 21 and transverse stiffened middle spring'portion. 20, will generally be unobjectionable and although in some instances it might be 7 undesirable this pince-nez. illustrated in Figs. 5 and 6 is recommended. by its extreme simplicity of construction.

The modified construction of pince-nez illustrated in Figs. 7 and 8 resemble generally that illustrated in Figs. 1 and .2 but differs therefrom in the particulars now to be noted. In the constructionillustrated in Figs. 7 and 8 the lens-supports 25 at their upper ends are soldered or otherwise suit-ably attached to the rear face of a'horizontally arranged curved spring member having a wider and stiffened central portion 26 which tapers into narrower resilient end portions 27 which are turned downwardly and widened to form plackets 28, substantially the sameas in all of the hereinbefore described constructions. Placketeoperating.

lever arms 29 are shown as attached by" 7 means of rivets, and they also may be soldered or otherwise attached, to the upper ends of the plackets 28, and the lever arms 29 extend forwardly and are shown as pivoted by meansof pivot screws 30 to lugs 31 projecting from and which may be soldered or otherwise suitably attached to the upper ends of the lens-supports 25 adjacent to the ends of the stiffened portion 26 of the spring member. It will be noted that the prin cipal difference between this construction and that illustratedin Figs. 1 and 2 is that the lenssupports 25 and the placketbperat ing arms29, as well as the lever-supporting pivot lugs 31, are made of separate pieces of metal from the spring member and are attached to such spring member, which in the present construction has the stiffened transverse middle connecting portion 26 and the resilient curved ends 27 which are continued In use the operation is substantially the same as in the first described construction.

The further modified construction of my invention illustrated in Figs. 9 and 10 bears a similar relation to the construction illustrated in Figs. 3 and 4 that. the construction the construction illustrated in Figs. 9 and 10, placket-operating lever arms 32 are pivoted upon the lower horizontal ends of lenssupports 33, the inner or rear ends of the lever arms 32 being soldered or riveted, as shown, or otherwise suitably attached at points near the middle of plackets 34 which form continuations of resilient horizontally curved spring ends 35 of a curved horizontally arranged spring member having a middle transverse stiffened portion 36, to the rear face of which near the ends thereof the upper ends of the lens-supports 33 are soldered or otherwise securely attached, as appears in the drawings. This construction differs from that illustrated in Figs. 7 and 8, in that the placket-operating lever arms 32 are pivoted upon the lower horizontal ends of the lens-supports 33 and are attached to middle points of the plackets 34. The operation in use is substantially the same as that of the hereinbefore described constructions.

It is obvious that Various modifications may be made in the constructions illustrated in the drawings and above particularly described within the principle and scope of my invention.
